Wayfarer International Class Rules
April 1, 2018: Authority: Wayfarer International
Abbreviations used in these Rules:
1.1 The intention of the class rules is to ensure racing within the class on even terms whilst maintaining the boats characteristics of constructional strength, ease of handling, suitability for family sailing and day cruising and moderate cost.
1.2 The official language of the class is English and in the event of dispute over interpretation the English text shall prevail.
1.3 These rules are complementary to the official drawings and specifications. Any interpretation shall be made by the governing Wayfarer National Class Association (NCA) which shall subsequently notify the Wayfarer International Committee (WIC).
1.4 The constitution of the WIC governs the procedure for changing any of these rules.
1.5 The official drawings and specifications are made and the class rules are enforced (or their enforcement may be waived) without responsibility on the part of any member of the WIC, or any member of any NCA or the designer of the Wayfarer, or the copyright holder for the time being of the Wayfarer design, for any injury, loss or damage howsoever caused.
2.1 Only professional builders holding licences from the copyright holders of the Wayfarer design are entitled to manufacture constructors kits or build Wayfarer dinghies. A list of such licensees is obtainable from the NCAs. The assembly of boats from constructors kits or sub-assembled hulls may be performed by amateur builders.
2.2 Licensees are required by the licence to produce boats and constructors kits and parts in accordance with the official drawings and the specifications, issued by the copyright holders to the licensees, WIC and the NCAs, and with these rules.
2.3 Hulls and other components moulded in glass fibre reinforced plastics (GRP) shall originate only from official moulds. These are
moulds registered by the copyright holders as having been derived from the master plugs or official drawings. An NCA shall have the right to measure these moulds.
2.4 Boats built from constructors kits shall be assembled from components supplied by the licensees and shall closely comply with the official drawings. Wooden hulls built from constructors kits shall be built only on registered jigs supplied on loan with the kit. The use of other jigs or components or materials is prohibited. The following wooden items are exempted from the requirements of this rule: centreboards, rudder blades, rudder stocks, masts and booms, but shall comply with the relevant rules 17, 18, 26, 27.
2.5 Deviations from the official drawings and specifications are prohibited save for the following:
(a) Running rigging arrangements;
This rule also applies to repairs which shall additionally comply with Rule 5 and the Rules of Section III.
2.6 Subject to Rule 2.5, amateur or unlicensed builders may carry out repairs and the replacement of wood parts which have deteriorated.
2.7 Any repairs and or replacement of wooden parts which involve the removal of any bulkheads, transom, framing, stringers, hog, and centreboard case or any substantial part thereof, and or employs any jig, framework or other such device to maintain the boat's shape shall not be undertaken without prior authorization from the NCA except when this work is undertaken by a licensed builder.
2.8 Any work undertaken as defined in 2.7 shall ensure that the original hull shape is maintained and or the hull shape and materials meet specification.
3.1 The licensee is required by the licence to pay, on each boat or kit sold, the NCA registration fee and membership subscription for one year.
3.2 The boat will then be entered in the register maintained by the NCA. On notification of change of ownership the NCA will amend the register without charge.
3.3 A boat built in a country having no NCA shall be registered with the WIC which shall act as its NCA for the purposes of Rules 2, 4 and 5.
4 No boat shall be allowed to race
as a Wayfarer unless it is registered with an NCA in
the name of the current owner and has a valid
measurement certificate (hereafter referred to as
the certificate). The initial certificate shall be
issued by the NCA on receipt from the owner, or his
representative, of two copies of an official class
measurement form properly completed in accordance
with rule 5. One copy will be returned to the owner
with his certificate. On change of ownership a fee
is payable to the NCA for the issue of a new
5.1 This is a one-design class. Measurement tolerances are intended to allow for genuine building errors and shall not be deliberately used to alter the design. Measurement shall be carried out using these rules. The measurer shall report on the measurement form anything which he considers to be a departure from the intended nature and design of the boat or to be against the general interest of the class.
5.2 Only measurers individually approved by the NCA, or belonging to groups specified by the NCA, shall be authorised to measure Wayfarers. Payment for the measurers services shall be the responsibility of the owner.
5.3 A measurer shall not be authorised to measure a boat owned or built by himself or in which he has a vested interest.
5.4 Two copies of the official class measurement form properly completed in accordance with these rules shall be signed by the builder, official measurer and owner.
5.5 All sails shall be measured. Conforming sails shall be signed and dated by the measurer, and in countries using official stamps, shall also be stamped by the measurer.
5.6 The current rules which are not printed in italics shall apply to all boats; except that if a boat made prior to the effective date of the current rules fails to comply with any measurement control in Section III, it shall in this respect comply with the corresponding rules in force at the time when the boat was made.
5.7 The current rules which are printed in italics shall apply to all boats irrespective of date of manufacture or installation of equipment.
5.8 Any alteration or replacement shall comply with the rules current at the time of the alteration or replacement.
5.9 Certain measurements are required to be officially measured and entered in the measurement form, but this does not exonerate non-compliance with the remaining measurement rules.
5.10 It shall be the responsibility of the owner to ensure that the boat is measured and to ensure that it continues to comply with the class rules.
5.11 Any certified boat shall be liable to remeasurement at the discretion of the NCA or race committee, but only by an approved measurer.
5.12 The certificate is liable to be invalidated by repairs or replacements to items covered by the measurement rules. The boat shall be remeasured in respect of the affected part by an official measurer and the certificate endorsed accordingly. Repairs or replacements will normally be recorded on an official measurement form but in these cases the forms are not required to be recorded with the NCA.
5.13 Cases of doubt regarding compliance with the class rules shall be referred to the committee of the NCA who shall give a ruling.
5.14 An NCA is empowered to grant dispensation in exceptional cases where this is considered to be in the interests of the class. Any such dispensation shall be recorded on the certificate of the boat concerned.
5.15 Rulings under 5.13 and dispensations under 5.14 shall be communicated to the WIC by the NCA concerned.
5.16 The re-registration of a boat shall be permitted, and a licence plate issued, given the following conditions:
(a) When proof of registration has been lost.
(b) Confirmation of ownership has been verified by the NCA.
(c) The boat is measured and conforms to the class rules in full.
(d) The NCA is informed that the ruling 5.16 is being sought prior to measurement.
(e) The boat number issued shall be prefixed by numeral 0.
(f) The number shall also be permanently etched into the GRP in a clearly visible position.
(g) A class measurer shall confirm to the NCA that the licence plate is fixed to the hull and rule 5.16 (f) is complied with before a certificate is issued.
